The Smugglers is the dull as shit opening to Season 4 of Foctor Gru. It features the first trip of Ben and Polly "you can't enjoy us as companions because the BBC are nazis" in the TARDIS, as well as nothing interesting at all.
So Ben and Polly break into the TARDIS, not unlike most of the First Doctor's companions. The travelers are whisked off to seventeenth century Cornwall, which is duller than it sounds. They accidentally interrupt a suicidal church wardens drunken binge, and he mistakenly tells the Doctor some total bullshit that causes a lot of problems.
Anyways, some pirates show up looking for some treasure, which you think would be interesting, but Hayles manages to make it bland as fuck. No joke, I fell asleep during episode 3, which isn't even the dullest of the four. Ben and Polly and the Doctor are separated, because no one knows how to write historicals in any other way. Some more bullshit happens, Blake shows up with some Militiamen, there's a battle, and almost everyone dies while the Doctor, Ben, and Polly laugh it all of in the TARDIS. Of course, the joke is on the Doctor, because his number is up next.
Features a white master beating and killing his black subordinate. Of course, you don't hear the SJW's scream about this because they're too lazy to watch the LC reconstructions of missing episodes due to the fact that they aren't true fans.
There really isn't that much to say, because not that much happened. It's definitely the weakest premiere so far, and it's kind of disappointing that this is ol' Billy's penultimate episode, but what can you do? Not fall asleep watching it like I did, that's what.
